Seasonal air–sea CO2 fluxes in the southern California Current off the Baja California Peninsula (Mexico)

Seasonal climatology of air–sea CO2 exchange was estimated from in situ sea surface CO2 partial pressure, temperature, salinity, and satellite wind data obtained from 2004 to 2011 in the southern region of the California Current, off the Baja California Peninsula (Mexico). The average annual CO2 flu...

The average annual CO2 flux indicates that the study area is a source of CO2 to the atmosphere (0.65 mmol m–2 d–1). It changes from being a source in summer (2.33 mmol m–2 d–1) and autumn (0.92 mmol m–2 d–1) to acting as a sink in winter (–0.26 mmol m–2 d–1) and spring (–0.37 mmol m–2 d–1). The area to the north of latitud 28ºN (off Punta Eugenia) is a CO2 sink (–0.42 mmol m–2 d–1), whereas the area to the south of this latitude is a source of CO2 to the atmosphere (1.80 mmol m–2 d–1), mostly due to thermodynamic effects. The northern coastal zone is a permanent CO2 sink (–1.29 mmol m–2 d–1). During the 2004 El Niño event the whole area contributed 2.00 mmol m–2 d–1 of CO2 to the atmosphere, but during the 2011 La Niña the ocean absorbed 5.30 mmol m–2 d–1 as a result of physical and biological dynamics. The seasonalcycle is dominated by temperature rather than biological effects, except in the northern coastal area. It is necessary to continue with in situ measurements of the CO2 system to have solid foundations to estimate the effect of the long-term increase in dissolved inorganic carbon onmarine organisms. La climatología estacional del flujo de CO2 entre el mar y la atmósfera en la región sur de la corriente de California, frente a la península de Baja California, fue calculada con datos in situ de la presión parcial de CO2, temperatura y salinidad recolectados de 2004 a 2011. Según el promedio anual del flujo de CO2 (0.65 mmol m–2 d–1), la zona de estudio es una fuente de CO2 a la atmósfera, y cambia de ser fuente en verano (2.33 mmol m–2 d–1) y otoño (0.92 mmol m–2 d–1) a ser sumidero en invierno (–0.26 mmol m–2 d–1) y primavera (–0.37 mmol m–2 d–1).La zona al norte de la latitud 28ºN (frente a punta Eugenia) presenta condiciones de sumidero de CO2 (–0.42 mmol m–2 d–1), mientras que la zona al sur de esta latitud se manifiesta como una fuente de CO2 a la atmósfera (1.80 mmol m–2 d–1), lo cual es atribuible mayormente al efecto termodinámico. La zona costera norte es un sumidero permanente de CO2 (–1.29 mmol m–2 d–1). Durante el evento de El Niño 2004 el océano aportó 2.00 mmol m–2 d–1 de CO2 hacia la atmósfera, y durante el evento de La Niña 2011 el océano incorporó 5.30 mmol m–2 d–1 debido a un efecto combinado de factores físicos y biológicos. En el ciclo estacional predominaron los efectos de la temperatura en vez de los efectos biológicos, excepto en la zona costera norte. Es necesario continuar con las mediciones in situ del sistema del CO2 para contar con bases sólidas que permitan estimar el efecto del aumento a largo plazo del carbono inorgánico disuelto del océano sobre los organismos. 2016-09-15 2021-06-03T03:55:32Z 2021-06-03T03:55:32Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2651 10.7773/cm.v42i3.2651 https://hdl.handle.net/20.500.12930/7508 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2651/1601 Copyright (c) 2016 Ciencias Marinas application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 42 No. 3 (2016); 155-177 Ciencias Marinas; Vol. 42 Núm. 3 (2016); 155-177 2395-9053 0185-3880
